Everyone, even those who don’t know anything about watches, knows that Rolex is one of the most respected and revered brands in the field. But few have any idea of what actually goes into a Rolex (literally, in this case), which is why this Rolex Submariner watchmaking demonstration video from Watchfinder & Co. is so fascinating.

The video shows Watchfinder & Co. Head Watchmaker Tony Williams taking apart and then reassembling a Rolex Submariner, considered by many to be one of the greatest sport watches of all time. But you don’t have to be a watch buff to appreciate the video, which is hypnotic in its depiction of the precision required to reconstruct a Rolex watch.
